You could always do it the hard way. Look to see what injector part#'s it has installed, what turbo model, then try installing the different wedges into the overhead cams to see if it set at 4,6 or 6,6 or 7,6 or some other combination thereof. There were several variations and a program that does not match can be problematic. - A mechanic has to be a complete moron to think they are all the same.
